An electric dipole is placed in an electric field generated by a point charge.

The torque on the dipole due to the field may be zero. Torque acting on a dipole placed in an electric field, \tau = r $\times$ F = rF\sin$\theta$, where $\theta$ is the angle between the force F and the arm of the couple. So, for $\theta$ = 0 or pi ,the torque will be zero. Hence, the amount of torque acting on the dipole depends on the orientation of the dipole in the given electric field.
